Enterprise JavaBeans was recently voted "Best Java Book" by the editors and readers of Java Developer's Journal. Readers of JavaPro named it the "Best Java Book for Experts." And Amazon.com included it in the Top Computer Books for 2000. Now the best only gets better! In the new 3rd edition, Enterprise JavaBeans has been completely revised and updated with a thorough introduction to the new 2.0 version of the EJB specification. Significantly different from the earlier version, the 2.0 specification introduces three dramatic improvements: A completely new version of container-managed persistence; local interfaces; and a totally new kind of bean called the "message driven bean." The new version of container-managed persistence (CMP) beans in 2.0 is more portable and robust than in the older 1.1 version. Most significant is the introduction of the relationship fields, which allow entity beans to declare relationships with each other as natural references. In order to make this huge leap in component relationships possible, EJB 2.0 had to redesign how entity beans are defined and interact. Our new 3rd edition examines this critical CMP model in detail.
